With respect to the microwave, the mix was accidental (very unscientific I know), Chris was trying to replicate it on Sunday but without joy. We are going to spend some time this week in a more analytical fashion to establish different material recipes and properties.

From what I can remember the original microwave success came from the following approximate recipe:

1 part water

1 part starch

splash glycerine

bigger splash vinegar

Microwave for too long until you have a gel rather than a liquid. Spread thin and microwave again in 30 second bursts until dry.

The second time around we didn’t cook it for too long, spread the plastic in liquid for and then zapped it periodically in 30 second bursts.

Like I said, not very scientific.

Peel off (nb may still be gooey on underside but this makes it fun for throwing at windows and people – allow to cool first).
